SHA-1 is a cryptographic hash.  It costs quite a bit to compute and is
only worth it if you need cryptographic properties.

SHA-1 may not be secure enough for cryptographic purposes.  There is a
real need for a new crypto hash that is safe.  I think Red Hat has
switched the SHA-256 for at least some purposes.
